Teardown Update! Just like we found in the iPhone 6s, the logic board's connectors are protected by tiny silicone seals.

These appear to be the waterproof silicon seals that Apple patented back in March.

The most common point of failure on a phone dropped in water? The logic board connectors. Coincidence? I think not.

Recent tests have proved that water resistance is greatly improved in the new iPhone 6s and 6s Plus. But why did Apple not mention anything about waterproofing on their new product?
